Abstract

A method for frustrating piracy of a movie, the movie including a plurality of filmed frames, each of the filmed frames including an image, the method including editing the movie prior to projection such that different regions of the image of one of the filmed frames are in different frames so that the different regions will be projected at different times, and repeating the editing for other ones of the filmed frames. Related apparatus and methods are also described.

1. A method for frustrating piracy of a movie, the movie including a plurality of filmed frames, each of the filmed frames including an image, the method comprising:
 editing the movie prior to projection such that different regions of the image of one of the filmed frames are in different frames so that the different regions will be projected at different times; and 
 repeating the editing for other ones of the filmed frames. 
 
     
     
       2. The method according to  claim 1 , wherein the different regions are non-intersecting regions of the image of the one filmed frame. 
     
     
       3. The method according to  claim 1 , further comprising physically duplicating the one filmed frame yielding a first projected frame and a second projected frame, the first projected frame including one of the different regions, the second projected frame including another of the different regions. 
     
     
       4. The method according to  claim 3 , wherein the editing includes editing out at least one region in each of the first projected frame and the second projected frame leaving behind the different regions. 
     
     
       5. The method according to  claim 1 , further comprising analyzing the image of the one filmed frame in order to decide a most suitable way to divide up the image of the one filmed frame thereby determining the different regions. 
     
     
       6. The method according to  claim 1 , wherein a shape of at least one of the different regions changes between the one filmed frame and another one of the filmed frames. 
     
     
       7. The method according to  claim 1 , wherein a location of at least one of the different regions changes between the one filmed frame and another one of the filmed frames. 
     
     
       8. The method according to  claim 1 , wherein an orientation of at least one of the different regions changes between the one filmed frame and another one of the filmed frames. 
     
     
       9. A tangible film medium including a movie edited by the method of  claim 1 .
